hotdeploy

I am using eclipse server capability for hot code deployment. Using tomcat as web server. But i am not sure how it works. I have my own understanding how it must be working internally. My understanding :- When developer make the changes in code(say class Employee), Eclipse will place/publish the modified compiled class at right location(must be specific web/app server. lets call it hot deploy directory(HDD)) under webserver. Now web server specific class loader will come in to picture. It finds the new entry under HDD. Now, it finds if class has been already loaded by classloader in perm gen

I'm using NetBeans 6.8, Tomcat 6, and Maven 2.2 and want to see changes in my code immediately in the browser (showing http://localhost:8080 ) after saving the file. The tomcat-maven-plugin has the following configuration: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>tomcat-maven-plugin</artifactId> <version>1.0-beta-1</version> </plugin> Following to the output it should perform in-place deployment. What can I do to see changes in my Java code immediately in the browser? I spent a lot of time trying to get this work. Finally I just used jetty. I put this: <plugin> <groupId>org

"Hot Code Replace Failed - add method not implemented". I get this error message every time I change something in my test class (and save it). Can't figure out what it means. Can somebody help? Possibly, you have a test which is still running (in debug mode). Try finishing all tests (you can see them in the debug view: window->show view->debug) and try again... VonC See this thread: This means you changed a class while it was debugging an application and it could not update the class for the application while it was running. The error suggests you may be running an older JVM, i.e. pre-1.4.2

I've got a pretty annoying problem with my JBoss AS 4.2.3 GA. Until recently everything was running fine, but now the hot deploy feature is now longer working. And -- as always -- I don't know what I did to cause this behaviour. My projects are built with Maven. I've cleaned every target directory, installed the projects and then deployed them to the server. So the sources in Eclipse and the deployed projects on the server should be identical. Inside a method I've added a simple System.out.println("test"); statement and -- BANG! -- I get the following error: (source: imagefruity.com ) Do you

I want to be able to deploy code changes to Tomcat (near instantly), while I'm developing in Eclipse. So far, I have my output from Eclipse placing the built classes in the WEB-INF/classes folder of my web application. I also have a reloadable context, with the web.xml as a watched resource. Any edit / save to this file does reload my web app, taking just over one second - much quicker than building a new war file and deploying it in full. However, what I'd like to do is trigger the redeploy when I edit any source file. As the .class files are being modified in Tomcat, it seems I just need to

I have a Spring Roo project and I use mvn jetty:run to run my app. The only problem is changes to the *.java classes do not hot deploy, while changes to *.jspx hot deploy fine. So how can I configure mvn jetty to hotdeploy for java classes? You need to set the scanIntervalSeconds to a value greater than 0 to enable it: scanIntervalSeconds - The interval in seconds to scan the webapp for changes and restart the context if necessary. Ignored if reload is enabled. Disabled by default. Default value is : 0. So the configuration might looks like this: <plugin> <groupId>org.mortbay.jetty</groupId>
